#include <bits/stdc++.h>
using namespace std;
typedef long long ll;
void solve(){
   string str;
   cin >> str;
   vector<int>ve;
   int len = 0;
   for(int i = 0;i<str.size();i++){
        if(str[i] == '1'){
            len++;
        }
        else{
            if(len != 0)ve.push_back(len);
            len = 0;
        }
   }
   if(len != 0)ve.push_back(len);
   double ans = 0;
   for(auto x : ve){
        if(x & 1){
            ans += (x + 1)/2;
        }
        else{
            ans += (x - 1)/2 + sqrt(2);
        }
   }
   printf("%.9lf",ans);
}
int main(){
    int t;
    t = 1;
    while(t--){
        solve();
    }
}

这程序好像有点Bug,我给组数据试试?
